This review examines the benefits and costs of outreach in a range of specialties and in a variety of settings. Simple 'shifted outpatients' styles of specialist outreach were shown to improve access, but there was no evidence of their impact on health outcomes. Outreach as part of more complex multifaceted interventions involving primary care collaborations, education and other services was associated with improved health outcomes, more efficient and guideline-consistent care, and less use of inpatient services. There is a need for better quality evidence evaluating specialist outreach in all settings, but especially in rural and disadvantaged populations.
閱讀完整摘要
Specialist medical practitioners have conducted clinics in primary care and rural hospital settings for a variety of reasons in many different countries. Such clinics have been regarded as an important policy option for increasing the accessibility and effectiveness of specialist services and their integration with primary care services.
目的
To undertake a descriptive overview of studies of specialist outreach clinics and to assess the effectiveness of specialist outreach clinics on access, quality, health outcomes, patient satisfaction, use of services, and costs.
搜尋策略
We searched the Cochrane Effective Practice and Organisation of Care (EPOC) specialised register (March 2002), the Cochrane Controlled Trials Register (CCTR) (Cochrane Library Issue 1, 2002), MEDLINE (including HealthStar) (1966 to May 2002), EMBASE (1988 to March 2002), CINAHL (1982 to March 2002), the Primary-Secondary Care Database previously maintained by the Centre for Primary Care Research in the Department of General Practice at the University of Manchester, a collection of studies from the UK collated in "Specialist Outreach Clinics in General Practice" (Roland 1998), and the reference lists of all retrieved articles.
選擇標準
Randomised trials, controlled before and after studies and interrupted time series analyses of visiting specialist outreach clinics in primary care or rural hospital settings, either providing simple consultations or as part of complex multifaceted interventions. The participants were patients, specialists, and primary care providers. The outcomes included objective measures of access, quality, health outcomes, satisfaction, service use, and cost.
資料收集與分析
Four reviewers working in pairs independently extracted data and assessed study quality.
主要結果
73 outreach interventions were identified covering many specialties, countries and settings. Nine studies met the inclusion criteria. Most comparative studies came from urban non-disadvantaged populations in developed countries. Simple 'shifted outpatients' styles of specialist outreach were shown to improve access, but there was no evidence of impact on health outcomes. Specialist outreach as part of more complex multifaceted interventions involving collaboration with primary care, education or other services wasassociated with improved health outcomes, more efficient and guideline-consistent care, and less use of inpatient services. The additional costs of outreach may be balanced by improved health outcomes.
作者結論
This review supports the hypothesis that specialist outreach can improve access, outcomes and service use, especially when delivered as part of a multifaceted intervention. The benefits of simple outreach models in urban non-disadvantaged settings seem small. There is a need for good comparative studies of outreach in rural and disadvantaged settings where outreach may confer most benefit to access and health outcomes.
